EF Johnson Model 145-202-2 Heavy Duty Servo Controlled DPDT RF Contact Switch Rated 22 KV, 25 Amps @ 2 MHz

This EF Johnson Model 145-202-2 Heavy Duty Servo Controlled DPDT RF Contact Switch, is Rated 22 KV, 25 Amps @ 2 MHz 

 It has huge Silver plated contacts and two servos that can be used with 120 or 240 volts AC depending on how you wire the terminal strip.

 One servo pulls the switch bar one way and the other pulls it back the other way. 

 There are two micro switches that open when the initial switch is made, turning off the voltage to the servo once it is switched, and the same for the other servo.

I tested the unit on 120 volts AC and both servos are working and switching the unit as they should.

 There is a wiring diagram on the bottom of the unit.

 The base of the unit measures 11 by 8 inches and has rubber grommets for isolation and shock protection.

 It weighs 18 pounds.

 I have seen a single pole double throw on the surplus market for sale for nearly $1000.00

 This rare find is a bargain at under $100.00

 This seems like it would be a great switch for remotely switching antennas or any high power RF application.

I am selling it as is as described for the family of a silent key who was my friend.
